AUTOMATIC WEB-GUIDING DEVICE.

Specification of Letters Patent.

Application filed September 26, 1907.

Guiding Devices, of which the following is a specification, reference being had therein to t 1e accompanying drawings.

The present invention is m the nature of an improvement upon the automatic 'web.

guiding device which is described in United States Letters Patent No. 678,121, granted to me under date of July U, 1901. The device of the said patent acts to cause the selvages or margins of an advancing con tinuous weh ----of cloth, for instance-to follow along predctermined lines as the \\'(l) is operated upon, or wound it comprises, essentially, a detector-roll contrived to ascertain the. positions of the respective selvnges or margins of the web, traveling selvage-ha'rs or blocks, and autoinatie devices. under control of the said detector-roll whereby the said *sel vage-bars or blocks are adiusted transversely with rela-. tion to the width of the'web to correspond with the positions assumed by the respective selvages or margins on their way to the guiding device, and areoperated to conduct the respectivo sclvages or margins into'the predetermined paths.

In the machine described and shown in the patent aforesaid, the'radially-movable pins of the detector-roll are'spring-actuated, each pin having applied thereto a spring-13y which it normally is held in a position H1 which its outer end projects from the periph ery of the roll, in readiness to be pressed upon by a marginal portion of the Web. In the said machine, also, asthe detector-roll rotates the'inner ends of those are covered by the "maririnal portions of the web, andpressed radially inward thereby,

chine, or serve, as they are caused to travel n contact with the said cam-faces; to force the cam-sleeves and annuli outward from tl e middle, according; as the selvags or margins of the web sway inward or outward.

Serial No. aria-m0.

The present invention consistsin various features of improvement dispensing with the emplo rnent of springs in connection with the detector-pins of the detector-roll. Also, securing a quieter and easier action in effecting the automatic adiustment of the edge-positioning bars or blocks, or of the other edgeiositioning devices which may be employed ior the purpose of shiftin the selva es or margins of the web into t-e require paths. Also, largely reducing the opportunity and occasion for wear. Also,

involving a more convenient and advantageous construction of the principal working parts, and providing adjustments which enable certain important results to he attained in the use of the machine.

A machine embodying in preferred form the different features of the invention is illustrated in the drawings, in which latter,..

In addition, the machine is equip ed with directing and tension rods or rolls or guiding the web into the machine, to the detector-roll and edge-positioning devices, and from the machine, and producing in the web the pro or tension to secure the required action 0 'the detector and edge-positioning devices.

Having reference tothe drawings,at (1,.

Fig. 1, is indicated a web passing through the machine, the course of the said web, and the direction of its movement, being indicated b arrows in connection therewith in the S8.l( figure.

The machine-frame is designated 1.

At 2, Fi 1, is a guide-rod or roll mounted in the sai frame at the side where the web enters, and the web in passing into the machine being led under and part-way around the said guide-rod or roll.

At 3 is a rotatable guide and tensionroll having its journals mounted in bearings in the top of the maehine frame. The web passes from guide-rod or roll 2 upward to and partly around. roll 3, and from the latter asses downward to and part1 around the etector-ro'll 4. .From the rol 4 the web passes u ward to and around the upper portion of t a rotatable series of edge-positioning bars 5, 5, etc., and then to, under, and Elude-rod or roll 6 on its wa out of the mac ine.

eferring briefly to the features, in general,

of the machine -dn Fig. 3, which showscertain details 9f the construction at the end of the machine which is re resented in Fig; '1 7, 7, etc., are the radia y. movable detector members or pins of that and of the detectorroll 4 which s shown in such figure, and 8 is the cam-sleeve, or as it also may be termed, shifter-cam, that is employed at such end, the said cam-sleeve, or s ifter-cam, being mounted, as in the case of that of the atent of July 9 1901, upon theshaft, 9,"of t a de tector-roll with ca acit to move lengthwise with respect to t e s aft, but being held from rotation with the shaft. At 10 is a yoke, shown in place in the machine in Fig. l, and separately in detail in Figs. 8 and 9, a portion thereof being shown in section in ig. 3, the said yoke constituting a connector between the cam-sleeve or shifter-cam and the corresponding annulus shown at 11, and being connected ivotally with such annulus at the loading aid; of the center of the latter, and the annulus being arranged to swing transversely on .a ,vertical pivot 12 (Figs, 2, 10 and 11) located atthe opposite i. e. dolivory side of the said center.

The yoke, 10, as shown separately in detail in l igs. 8 and 9 is formed with a hub, 10', which fits upon the exterior of the outer end of the cam-sleeve and is made fast thereto.

livery si( e. The connection between the yoke and the leading side of the annulus is established by means of pivots which serve to join the arms l0", 10', with the arms 11*, 11". Arm ll uof the annulus carries or is provided with the ivot-pin 12. As in the patent aforesaid, t e parts just mentioned are duplicated at the respective sides of the machine, although in some instances I may employ only one sctof the said parts. At l3, 13, etc., Figs. 1 and 2 are the antifrietion rolls which are carried by the ed eositioning bars 5,5, elc., and engage with t 0 tracksurface 11 (Figs. 10 and 11) of the annulus. As in the said patent, the bars 5, 5, etc., are

arranged in a cylindrical series 11 on a rotating sup ort, and connected toget er in pairs (each 0 such pairs comprising a bar at the one end of therotating series and the corresponding bar at the other end of such series) by contracting spiral springs (shown at 72, 72, etc., in the patent) which tend to draw the said bars lengthwise toward the middle of the width of the machine so as to hold the rolls 13, 13, etc., in contact with the tracksurfaces of the respective annuli. As in the machine of the atent, the pressure which is transmitted t rough the said rolls to the annuli tends to swing each of the latter inward at its leading side, and opersleeve until such movement is limited by the detector-pins. Thereb in the same general manner as in the mac me of thepatent in question, the leadin side of each annulus is pressed inward at al times to the extent permitted by-the detector: ins at the corresponding side of the mac ine, that is to say, to an extent which at an given instant conforms to the line on w ich the selvage or margin at such side is traveling'in arriving at and assing u on the edge-positioning bars. Brie y 'descri ed, the rotating support for the edge-positioning bars 5, 5, etc., comprises, essentially, the rotatable shaft l4, Figs. 1 ,and 2, which is mounted in suitable bearings at 15, 15, in connection with the opposite side frames of the machine, the heads l6, 16, which are fixed upon the said shaft, and the guide-rods 17, 17, etc., having their 0 )posite ends fixed in the respective heads, tie said bars 5, 5, etc., being mounted upon the said uidarods with capncit' to slide upon the utter in the direction oi the length thereof.

The outer surfaces of the bars 5, etc., are

tor devices transversely of the machine to l adapt the machine to operate upon webs of dillcrcnt widths, and the movable members detecting action of the pins, it may be. stated that in the use of the machine the web a, in

l passing under and partly around the detector-roll, makes close contact with the periphery i the latter as indicated in Fig. 3.

.As the turning movement of the detector-roll I proceeds, in unison with the travel of the 1 web, and carries a given series of the detecintci'posed between such pins and the camf sleeve are illustrated in l ig. 3.

Fig. 3 shows a portion of the length of one end-section of thc detector-roll, the shell of the said end-section being fixed at its outer end upon the exterior surfaces of bars 19, 1!), etc, the said burs also extending in the direction of the length of the roll, and in turn being porti n of arms 2U, 2U, cttn, ol' the head 20 which is slcevcd upon the shaft ii.

For the rcccption ol' the dclcctor-pins, each l or it) has formed therein a series of radial holes 1!)", ill", cic., Figs. 6 and 7, constituting p ckets in which the detector-pins 7, 7., etc. the said pins arc movable radially. 'lhc por tion of the said shell which covers the said bars has formed ihcrcin holcs registering with those in the respective bars,and through which the out'crcnds oi the pins n at project.

in order to limit the extent of t he outward movement of the pins, the holes in the shell are made less in diameter than lhosc-in .the bars 1!), Hi, chm, and the outer portions of the pins are made smaller in diameter than the inner portions there f, a shoulder being formed at the cxtcrior of each pin at an intermediate point in the length of the lattcr. 'lhcrcln, when outward movement of the pins within their pockets occurs, the shoulders of the pins engage with the margins of the holes in the shell and prevent the pins from leaving the ockcts.

As previously indicated iii-rein, the springs of the pnlcnt of July .l, 190], employed in colllicclion with thc detector-pins for project ing them radially outward, are dispensed with undcr lhc present invention, and gravit alone is depended upon for causing the dcici-im pins to work radially in and out within the pockets. Thus, the detector-pins arc capablc oi l'rcc movement within their pockcls, so that as a given series of the pins is carried upward to thc top side of the detector-roll by rotation of the latter the pins will gravitalc inward, as at the top in Fig. 3, andthat in hcinsz carried around to the bottom side of the roll, they will tend to gravitate outward again, into the radial position of the outermost two pins in such ligure which are not restrained by the web (1..

Briefly summarizing tl'" incidents in the are contained, and within which i tor-pins around from the upper side of the roll downward to the lower side thereof, the pins of the said series tend to slide radially outward. Those thereof which occupy pockets that are covered or closed by the marginal portion of the web are supported by the web in approaching the lowermost position, and therelrv held inward, as represented in l ig. 3. Those pins which are beyond the selvage or margin of thc wcb are permitted to slide l downward and outward under the inlluente I of gravity until their nn'wcment radially outing sccnrcd upon thc longitudinally-cxtenih 1 Ward is arrested by engagement of their shoulders with the edges of the shell around the holes therein, as shown in Fig. 1% in he case oi the two outermost detector-pills.

For convenience in operating upon webs of diil'erent widths, the detector-roll is made of the wcll-known telescoping construction which is more or less common in the case of the rolls and cylinders employed in webhandling machines. Only the cndsection at one side of the machine is represented in Fig. 3. inasmuch as the general character of the .telescoping construction is well-ki'iown to those skilled in the art. By lengthening or shortening the roll the length thcrcol' is made to correspond approximately with the width of a given web to be operated upon, in the state of lateral extension in which it :ti'liYts at such roll, and thereby the series of deteci tor-pins at the respective ends of the roll are i ad usted into proper working positions with relation to the sclvagcs or margins oi the Web. Usually, the adjustment will be such that each sclvago or margin will travel at about mid-length oi the series of detectorpins. For the purpose of enabling the adjustment of the length of the detector-roll to be cllectcd conveniently, the head 20 is mounted upon shalt El with capacity to slide thcrcon in the dire tion of the length of such shalt, and a screw-thrcadcd adjusting shaft 2] is provided. The shall i) is hollow or tubular. and the screw-tiireadcd adjusting shal't extends lengthwise through the same. Bearings For th latter shaft are lit ted within the opposite ends of the hollow shall ll, one of such bearings bcin; shown at 22, Fig. 3. A crank-handle, 23, is fixed upon either or each end of the adiusting shall to enable the latter to be turned by hand. in connection with each endseetion of the detector-roll, a nut, 24, is employed within the hollow shaft 9. the said not being engaged with the threaded portion of the corresponding: end of the adjusting shaft, so that when the said shaft is turned the nut will be moved in the direction of the length of the hollow shaft. In order to transmit this movement to the corresponding section of the detector-roll, connection is established between the said nut 24 and the spider or head 20, 20, by means of a key, 25, which last is secured in lace within the hub of the said spider or sad by means of screws 26, 26, and provided at its op ilosite ends with projections extending radia y inward and receiving the nut between them. This key occupies a longitudinal slot, 27, formed in the shell of the hollow shaft 9, within which slot the key slides as the nut, spider or head, etc., are changed in position. The key serves also as a means of causing the end-section of roll4 to rotate in unison with the hollow shaft 9 when the latter is turned. The other end-section (not shown) of the detector-roll is similarly constructed and connected with the hollow shaft 9, and with the adjusting shaft 21, with the diflerence that the direction of the screwthread on the corresponding portion of the latter shaft is reversed, as usual in the like constructions, so that when the adjusting shaft is rotated the respective end-sections shall be adjusted simultaneously in opposite directions in order to increase or decrease the effective length of the detector-roll, according as the said sections are moved toward or away from each other.

It previously has been mentioned herein that in the case of the machine described in the patent of July 9, 1901, the inner ends of those pins which are covered and pressed radially inward by the marginal portions of the web engage directly with the cam-faces of the cam-sleeves that are employed in connection with the annuluses. In the present invention, I interpose a movable member between detector-pins and cam-face, and thereby avoid the results of direct engagement. The invention, in its broader phases, is not limited with respect to the )recise form and construction of this movalile interposed member, nor with respect to the precise relations between such member and the parts with which it cooperates. In the illustrated embodiment of the intention a longitudinal movable bar 22 is rovided in conjunction with each series of ti l detectorpins 7, 7, etc This bar constitutes, in the said embodiment, the movable interposed member aforesaid. ()n the one hand, it engages with the particular )in (of thc serics of detector-pins with which it cooperates) which indicates the position of the sol .age or margin. of the web, and on the other hand It co-acts with the cam-face of the camsleeve in substantially the same manner as a pin co-acts with the cam-face of. the sled. e in theprior patent for the purpose of determlnmg the osition of the corresponding annulus. Eac movable bar 28 is held in place close to the inner side of thacorrespending fixed bar 19 by means of gibs 29, 29, and is adapted to slide lengthwise upon these latter. To provide for engagement with the detector-pins, the exterior surface of the inner portion of the length of each bar 28 is dropped inward toward the axis of the detector-roll, relative to the corresponding surface of the outer portion of such length, producing a shoulder, 28, located at an intermediate point in the said length and facing toward the middle of the machine. This shoulder is adapted to enga e, in movement of the bar toward the mid le of the machine, with the inner end of the detector-pin Which is covered and held radially retracted bv the salvage or mar of the web a. See the lower portion of i 3. Each bar 28 carries a roll, 30, whic is mounted upon a studprojecting radially inward from the bar, and the cam-sleeve 8 is formed with a peripheralcam-groove at 8* receiving the rolls of the series of bars 28, 28, etc. The walls of the cam-groove are so shaped as to tend to move each shouldered bar in turn, in each rotation of the detectorroll, first toward the middle of. the machine, and then in the re :erse direction, namely, toward the end of the detector-roll. The movement toward the middle of the machine is timed to occur after the bar and the series of detectorins with which it co-acts have arrived at t e under side of the detector-roll, so as to afford those pins of the said series which are unconfined by the marginal portion of the web a full opportunity, before such mouement takes place, to gravitate into their outermost position, radially, as in the case of the outermost two pins in the lower part of Fig. 3. The movement of the bar 28 toward the middle of the machine, due to the action of the camgrades of the walls of the cam-groope of the cam-sleeve upon the roll 30, proceeds until the shoulder of the bar encounters a pin in radially retracted position. This encounter arrests such inward movement, and thereupon the said roll, as it is carried around by the d'etcctor roll in the rotation of the latter, acts by its pressure against the said cam-grades to force the cam-sleeve and the leading side of the connected annulus out ward away from the middle of the machine to the extent of the remainder of the throw of the cam-grades. The tension of the springs (72, 72, etc, in the )rior patent) by which the selvage bars or blocks are drawn toward the middle of the machine, and which is transmitted through the said bars or blocks and the anti-friction rolls 13, 13, etc, carried thereby to the annulus at each side of the machine, acts to oppose this outward movement of the cameve and annulus, and holds the shoulder of the bar pressed firmly against the pin with which it sway inward so that fewer pins of the sueit ceeding series ttl'C covered and held retracted thereby, to swing the annulus t ward the middle oi the machine and more the cumsleeve and assemblage of bars in the some direction until the shoulder of the ban eo1ning into action brings up liriuly against the inner end of the outermost pin thnt held retracted by the web. ()n the other llztlltl, should the sol age or nun-gin sn :rv out ward. the shoulder ol the hitter but will engage with H, pin l' the suill succeeding: series nearer the outer end of the detectoiu'oll, and by iii-resting the inwurd moauuent of the her before the (ItlIkgltHlHr-l (tense to net will bring about the. outward shift of the cumsleeve and lending side of the annulus which is necessary to place the annulus in proper working position.

To cinilile the delivery sides ol' the :in nuli at the opposite ends or sides of the imichino to be set or :u! iustcd nearer together or further epurt according: to the width of the Web to be. e u'ruted upon, or otherwise according' to t e distancibetween the paths which it is intended the up )osite selvziges or margins of the web shall follow in passing inward, each pivot-pin 13 is engugcd with :1. block 10, the hitter being mounted in manner enabling it to be shifted toward or from the middle of the machine. lliit'l) block it] lets an opening, unide horizontully thcrethrough, through which the arm 11 ot' the corresponding annulus projects. The pivot-pin 12 projects upwurd from the said u rm into it slot 401, Fig. l2, in the, cover or top of the said block. This slot permits the pivot to move forward or reurwurd as the annulus is turned or swung in being adjusted at its respcetive sides. 'lhe two blocks at the opposite sides of the machine are formed with sleeve-portions 41, ll, which lit upon a transversely extending rod or shul't 4'2 that is supported :it its ends by bearings with which the side-l'rzum-s ol' the machine are provided. The suid rod or shaft is formed with right end lel't scrcw threzuls near its respcctive ends, and the sleeves 41, 41, are internally threaded to engage the threads of the rod or shaft. By rotating the rod or shalt, as by means olthe handle 43, the blocks and the delivery sides of the unnuluses may be shifted nearer to or l'ztrthcr from each other.

1 inch. ennulus 1 l is formed art its receiving side with n receiving; section H which has the acting surface thereof concentiie with the pivots which"connect the annulus with the COI'l'tWSPUUtlilltI yoke It See the dotted lines in Fig. ll. As it consetpience of this concentricitv, the changes in the inclination of the annulus which occur from time to time in the Working of the machine, either as it result of the automatic adjustment of the yoke and annulus, or as a result ofthe adjustment by hand of the pivot 12, will have no effect upon the approach of the rolls 13 to the pivotal nxis. At the place at which the web passes on to the selvsige )ositioning bars or blocks, the rolls ulwuys will approach to within the same distance of the said pivotal axis, unaffected by the variation in inclination. Similarly, at the delivery-side, euch annulus is formed with it delivery-section 11 which has the ,zictiug surface thereof concentric with the axis of the pivot 12. As :i consequence, the distance horizontally between the rolls when in contact with such section and the line of the said uxis will be uiutil'ected by the movements of the annulus 2th it is swung in and out at the receiving side thereof by the action oi the :uitometic mechanism. The length of the concentric receiving and delivery sections 11, 1'1", is sullicient to erinit considerable latitude of variation in the height at which the web arrives upon the edge-positioning bars or blocks in passing from the delivery-roll, and also in the height :11 which the web leaves the said edge-positioning burs.

For the purpose of rotating the detectorroll and the series of positioning bars or blocks, :t sprmrket-wheel it) is lixed upon one end. of the hollow shalt .1, of the detectorroll, and n sprocket-wheel 51. is fixed upon the shaft Isl ol' the rotary series of bars or blocks. A band-pulley, 52, is mounted to turn upon it stud, 53, which is applied to one side-frame, 1, of the machine, this bundpulley being provided with 2], connected sprocket-wheel 54. A sprocket-chain, 55, passes around the sprocket-wheels 5t] and 54, and one rim thereof engages with the sprocket-wheel 51. then the said bandulley 52 and sprocket-wheel 54 are driven )y means of a. suitable driving-band applied to the former thereof, movement of rotation in themqniredulirections is transmitted by means of the sprocket-chain 55 and s noeketwheels 50 mid 51 .tolhe detector-roll and series of positioning bars or blocks.

it is to be understood that the essential function of the detector-roll, detector-members curried thereby, end eutonnitie adjusting mcens operating under control of the. said detector-111cmhers, is to bring about it relative shift between the edge of an advancing web and the devices or part to which the Web or the said edge is to be delivered, and that the features of invention in connection there with, broadly considered, are not necessarily restricted with respect to the particular construction of the parts above specified, or of the machine in which they are emplo ed, or to the precise manner in which the stud shift is attained.
